How Much Sound Penetrates from the Street

The Higher the Rw, the Quieter Your Living Space

Sound insulation Rw (airborne sound insulation) is a key parameter indicating how many decibels (dB) a building element (window, wall, door, ceiling) can reduce penetrating noise from the outside environment into the interior.

The higher the Rw value, the better the sound insulation. It is measured in decibels (dB).
